I grow in my closet in the bedroom, CFL grow, and at night I actually keep the door closed with a towel under the door so as to not leak light (I need complete darkness to sleep) but when I wake up, I'm diligent to open the door and let it ventilate. When it was summer, I would open a window and point the fan outward, but it's getting to be winter here and in the 30's so it's not really an option...so I got some ONA Blocks and just let it ventilate into my house. But I'm on 12/12 so the light leak isn't a problem for my sleep! But before the ONA Blocks dude, my room REAKED of skunk. Was kinda nice to walk into, but I'm growing Sour Diesel and it is so god damn skunky. My clothes also carry a small smell of weed in them though...
